CRISPR/Cas9 systems have great potential to achieve sophisticated gene therapy and cell engineering by editing multiple genomic loci. However, efficient multiplex editing, the delivery system needs adequate capacity transfect all RNA species at required stoichiometry into cytosol of each individual cell. Herein, inspired biomineralization in nature, we develop an all-in-one biomimetic mineralized system. This allows for precise control over coencapsulation ratio between Cas9 mRNA sgRNAs, while also exhibiting a high loading capacity. In addition, it enhances storage stability 4 °C up one month, surface nanoparticles can be easily functionalized targeting vivo nonliver sites. Based on above characteristics, as proof-of-concept, our was able significant gene-editing target (Survivin: 31.9%, PLK1: 24.41%, HPV: 23.2%) promote apoptosis HeLa cells mouse model, inhibiting tumor growth without obvious off-target effects liver tissue. addresses various challenges associated with multicomponent vivo, providing innovative strategy RNA-based editing.

Abstract The advent of SARS-CoV-2 variants with defined mutations that augment pathogenicity and/or increase immune evasiveness continues to stimulate global efforts improve vaccine formulation and efficacy. extraordinary advantages lipid nanoparticles (LNPs), including versatile design, scalability, reproducibility, make them ideal candidates for developing next-generation mRNA vaccines against circulating variants. Here, we assess the efficacy LNP-encapsulated booster encoding spike protein concern (Delta, Omicron) using a predecessor (YN2016C isolated from bats) strain elicit durable cross-protective neutralizing antibody responses. mRNA-LNP have desirable physicochemical characteristics, such as small size (~78 nm), low polydispersity index (<0.13), high encapsulation efficiency (>90%). We employ in vivo bioluminescence imaging illustrate capacity our LNPs induce robust expression secondary lymphoid organs.

Abstract Chimeric Ag receptor (CAR) NK cells are challenging to manufacture and fail achieve consistent tumor infiltration sustained cytolytic function in the microenvironment. In vivo engineering of using mRNA-based CAR delivery may overcome these issues. this study, we developed an programming method by designing CARs that leverage biology cell receptors for type–specific expression function. These were engineered fusion a recognition domain with natural cytotoxic family including NKp30, NKp44, NKp46. Our results demonstrated receptor–based can engage endogenous signaling adaptors effectively activate human lysis cytokine production. Specifically, discovered stable NKp44-based was contingent on presence immune cell–specific adaptor DAP12. This innovative strategy facilitates direct situ cells, enhancing safety minimizing off-target effects nontargeted, healthy tissues.
